spl: Implement IGeneralInterface GetConfig (#2705)
* spl: Implement IGeneralInterface GetConfig

This PR implement the GetConfig call of the spl service. This is currently needed for some homebrews which currently needs Ignore Missing Service to boot. Now it's fixed.
Implementation was done using Atmosphère code and REing too.

* Addresses gdkchan feedback
